# Graphing data that means something

## Goals

1. How to graph data
2. How to identify trends (linear data)
3. How to identify more complex trends (simple harmonic motion)
4. Discover that data doesn’t always tell you about a physical phenomenon: Most of the time we need to know what phenomenon we’re analyzing, before the data can be understood at all.

### Use the lesson ““Data has no meaning without a physical interpretation”

Actual student data

## Learning standards

A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012)
Dimension 1: Scientific and Engineering Practices.
Practice 4: Analyzing and Interpreting Data.
“Once collected, data must be presented in a form that can reveal any patterns and relationships and that allows results to be communicated to others. Because raw data as such have little meaning, a major practice of scientists is to organize and interpret data through tabulating, graphing, or statistical analysis. Such analysis can bring out the meaning of data—and their relevance—so that they may be used as evidence.”
